A municipal design needs some VNIs Layer-2 stretched between DCs while other tenants need Layer-3 reachability only. Which stretch approach is appropriate?
Select an answer to reveal the explanation.
Short Explanation
Tenants are not a monolith. Stretch the VNIs that truly need L2; give the rest L3-only—per VNI, on purpose.
Full Explanation
Selective stretch designs allow some VNIs or tenants to extend Layer-2 while others exchange only Layer-3 prefixes. That per-tenant or per-VNI choice matches mixed application needs without forcing a single stretch mode on the entire municipal fabric. Uniform stretch of every VNI is not required once any L2 stretch is introduced.
